Leviton Manufacturing Background

Founded in 1906 in Brooklyn, NY,

celebrating 100 years of success! Levitons first product was gas mantle tips

for gas lamps when the city of New Yorkinstalled gas lamps.

Isadore Leviton (pictured) was a partnerwith Thomas Edison.

Industrial, commercial, OEM andresidential markets

The average American home containsmore than 100 Leviton devices

In a major American city lit up at night,about 90% of the lights you see are

connected to some kind of Leviton device Leading supplier of electrical, lighting

IEEE 802.11n (Next Generation Wi Fi) January 2006, IEEE 802.11n Task Group approved the EWCs

specification as the draft approval of 802.11n

March2

006, 802

.11n draft sent to first letter ballot

May 2006, IEEE 802.11 Working Group rejected Draft 1.0 of theproposed standard

Final approval of standard is not due until July 2007(likely to be 1st

quarter2008)

Mid 2008, most vendors will have 802.11n products available


20/50

20 Confidential

IEEE 802.11n Benefits Performance in physical layer to reach 300 Mbps

Could offer up to 600 Mbps with 4 antennas

Could hit as much as 75% throughput of its raw data rate

Range will increase over existing Wi-Fi networks


21/50

21 Confidential

Should You Buy Pre N? No Upgrade guarantee: There is significant risk that equipment

shipped today will contain chips and firmware that cannot be upgradedto provide full compatibility with the final standard.

Could Interfere With Other Networks: chipmakers and the IEEE taskgroup working on 802.11n havent agreed on their approach to mitigateinterference with existing legacy Wi-Fi networks. Test methods on welltest in real world environments or with other devices.

Problems: poor interoperability, security model problems andperformance

Will need gigabit network Prices will plummet: Airgo is waiting, Intel plans unknown, Atheros,

Broadcom and Marvell now producing silicon expect a drop

IEEE 802.15 (Personal Area Networks) 802.15.1 Bluetooth

Provides a way to connect and exchange information between devices such

as PDAs, mobile phones, laptops, PCs, printers and digital cameras

802.15.3a UWB / Wireless USBUWB: A technology for transmitting information spread over a large

bandwidth that would be able to share spectrum with other users

Wireless USB: A short-ranged, high-bandwidth wireless extension to USBintended to combine the speed and security of wired technology with theease-of-use of wireless technology

802.15.4 ZigBeeA suite of high level communication protocols using small, low-power digitalradios based on the IEEE 802.15.4 standard for wireless personal areanetworks (WPANs)

Bluetooth Designed for low power consumption & short range

Utilizes low cost transceiver microchips in each device

Applications:-Wireless communication between a cell phone and a hands free headset-Wireless communications with PC input and output devices (I.E. mouse, keyboardand printer)-Replacement of traditional wired serial communications in test equipment, GPSreceivers and medical equipment-Wireless control of a game console such as Sony's PlayStation 3

Bluetooth 2.0 Backwards compatible with 1.x

Main enhancement is the introduction ofEnhanced Data Rate (EDR),up to 3.0 Mbps-3 times faster transmission speed (up to 10 times in certain cases)-Lower power consumption through a reduced duty cycle-Simplification of multi-link scenarios due to more available bandwidth-Improved BER (bit error rate) performance

UWB Federal Communications Commission (FCC) authorized the unlicensed use

of UWB in the 3.110.6 GHz band (2002)

Scalable in performance: 110 Mbps @ 10m and 480 Mbps @ 2m

Ultra Wideband causes significantly less interference th

an conventionalnarrowband radio solutions (result of broader spectrum, lower power andpulsed data)

Primary advantages of UWB are high data rates, low cost, and low power

The major drawback of UWB is that under current FCC regulations, it is

limited to 10, or a few 10s of meters, depending on the desired data rate

Status:-IEEE 802.15.3a task group (TG3a) members decided to withdraw the January 2003 ProjectAuthorization Request (PAR) that initiated the development of high data rate UWB standards.(January 2006)-It was decided to allow the market to move forward with the commercialization of multipleUWB technologies

UWB Primary Applications Home Entertainment Systems

IEEE 802.16 WiMAX (Broadband) WiMAX improves upon many of the limitations of the Wi-Fi

standard by providing increased bandwidth, range and strongerencryption

Most interest will probably be in the 802.16d and .16e standards,since the lower frequencies suffer less from signal attenuation andtherefore give improved range and in-building penetration

802.16e (Mobile WiMAX)

-Allows for fixed wireless and mobile Non Line of Sight (NLOS)applications primarily by enhancing the Orthogonal FrequencyDivision Multiple Access (OFDMA)

-Approved in December2005

Mesh Networking A way to route data, voice and instructions between nodes.

Allows for continuous connections and reconfiguration around

broken or blocked paths by "hopping" from node to node until thedestination is reached.

Allows inexpensive peer network nodes to supply back haulservices to other nodes in the same network.

The network can still operate even when a node breaks down or aconnection goes bad. I.E. self-healing.

802.1x An IEEE standard for port-based Network Access Control

Provides authentication to devices attached to a LAN port

Establishes a point-to-point connection and prevents access from thatport if authentication fails

Used for certain closed wireless access points and is based on EAP

RADIUS (Remote Authentication Dial InUser Service)

An AAA (authentication, authorization and accounting) protocol forapplications such as network access or IP mobility.

RADIUS is a common authentication protocol utilized by the802.1x security standard (often used in wireless networks).

The DIAMETER protocol is the planned replacement for RADIUS.DIAMETER uses TCP (Transmission Control Protocol) whileRADIUS uses UDP (User Datagram Protocol) as the transport

layer.

WPA & WPA2 A class of systems to secure wireless (Wi-Fi) computer networks.

Created in response to weaknesses researchers had found in the previous system,WEP.

WPA is designed to work with all wireless network interface cards, but notnecessarily with first generation wireless access points.

WPA2 implements the full (802.11i) standard, but will not work with some oldernetwork cards.

WPA is designed for use with an IEEE 802.1x authentication server, whichdistributes different keys to each user. However, it can also be used in a lesssecure "pre-shared key" (PSK) mode, where every user is given the same

passphrase. WPA2 certification is mandatory for all new devices wishing to be Wi Fi

certified.

WPA2 is also known as 802.11i

Camera saves $$$ and time

Eliminates bulky AC adapters simplifies installation

IEEE standards compliant technology safe and reliable

Low DC Voltage = safe power feeding

Why use a MidspanWhy use a Midspan?

Large installed base of Ethernet switches.

Keep the existing Ethernet infrastructure to save costs.

Easy to install without re-wiring the rack (doesnt affect testing).

Optimizes PoE port expenditure. Purchase the PoE ports you need. Optimal solution for low density applications.

Support the bottom-up approach of typical net installations

Start with small test installations (using existing data

infrastructure) before a large deployment

IEEE 802.3at (PoE Plus) Most optimistic estimate for approval in early 2007

Support power delivery with 10M, 100M, 1G and perhaps even 10Gbpsdata delivery

802.3at should operate on CAT5 (24AWG) and thicker copperinfrastructure such as Cat.6 (23AWG) or Cat.6a (22 AWG), unlike802.3af, that had take into account the CAT3 limitations

802.3at should follow the power safety rules and limitations pertinent to802.3af

A 802.3at PSE must be backwards compatible with 802.3af, being ableto power both 802.3af and 802.3at PDs

802.3at should provide the maximum power to PDs as allowed withinpractical limits, at least 30W

802.3at PDs, when connected to a legacy 802.3af PSE, will provide the

user an indication that a 802.3at PSE is required.
